Description

Super large still-pressure dynamic replacement is hammered into shape

Technical field

The utility model belongs to construction machine field, is related to strong rammer hammer.

Background technology

The hammer ram still-pressure that the processing of existing market dynamic replacement uses is generally 60Kpa ~ 120Kpa.It is chiefly used in handling shallow Layer foundation in saturated soft soil engineering.Hammer ram is sling using crawler crane tool, then breaking off relations falls, and hammer body does the movement of falling object Certain impact energy is generated to pending ground.Impact energy squeezes into the material strength of the better performances such as rubble, slabstone, slag In ground, pellet pier one by one is formed in ground, native form compound foundation between pier and pier, to improve foundation bearing capacity, Reduce sedimentation.During dynamic replacement, soil structures are destroyed, and foundation soil body generates excess pore water pressure, but with the time Increase, earth structure strength can be restored.Pellet pier generally has preferable water penetration, is conducive to excess pore water pressure in the soil body It dissipates and generates consolidation.

At present use as shown in Figure 1, hammer ram 1 basal diameter be 220cm, be highly 90cm, the height of tup 2 is 57cm, this hammer ram are only used for reinforcing shallow poor subsoil ground since still-pressure is too small.For high saturation silt and stickiness Soil processing depth is shallower, and especially for the more demanding engineering of foundation bearing capacity, this hammer ram can not meet design requirement.

Invention content

The purpose of the utility model is to overcome existing hammer ram there are the shortcomings that, it is big to provide a kind of impact energy, can make ground The deeper super large still-pressure dynamic replacement hammer of depth of base processing.

Technical solution used by the utility model is hammered into shape for a kind of super large still-pressure dynamic replacement, is characterized by it and is wrapped Hammer ram, tup are included, the total height of a diameter of 120cm of hammer ram, hammer ram are 420cm.

The utility model increases the height of hammer ram to increase the impact energy of unit area by the floor space of reduction hammer ram Amount so that the depth of basement process is deeper, and the still-pressure of hammer ram makes up to 300Kpa, treated Di base Cheng Zai Li≤ 500Kpa。

Tup height is 58cm.

Hammer ram is made of pedestal 11, fixed link 12, polylith hammer leaf 13, and fixed link is fixed on the base, and is machined on hammer leaf With the matched through-hole of fixed link, hammer leaf is sleeved on fixed link, and a piece of hammer leaf is connected with below tup, and tup connects with fixed link It connects.In order to make, convenient in carrying, multi-block thin slice, Assembling is made in hammer ram, and tup, pedestal working environment are disliked the most It is bad, it is easily damaged, part replacement is only used as when safeguarding, it is cost-effective.

The first-class angle of circumference of pedestal is disposed with four fixed links.Uniform force.

The height of every piece of hammer leaf of hammer ram is 15cm.

The utility model, by reducing the floor space of hammer ram, increases the height of hammer ram to increase unit plane under equal volume Long-pending impact energy increases the still-pressure of hammer ram so that the depth of basement process is deeper, while it is thin that polylith is made in hammer ram Piece, Assembling are conducive to make, carry and safeguard, cost-effective.

Specific implementation mode

The utility model is further illustrated below in conjunction with the accompanying drawings

As shown in Figure 2-5, a kind of super large still-pressure dynamic replacement hammer, it includes hammer ram 1, tup 2, hammer ram it is a diameter of The total height of 120cm, hammer ram are 420cm, and tup height is 58cm.Hammer ram is by pedestal 11, fixed link 12,13 groups of polylith hammer leaf At four fixed link equal circumference angles are uniformly fixed on the base, substructure height 15cm, are machined on hammer leaf and are matched with fixed link The through-hole of conjunction, the height of every piece of hammer leaf are 15cm, and hammer leaf is sleeved on fixed link, are connected with a piece of hammer leaf below tup, tup with Fixed link connects.

Hammer ram still-pressure after engineered is more than 300Kpa, and tamping energy is more than 3000KN.m after hammer ram elevated height 10m, Processing depth is 3m-5m.The impact energy for improving identical height unit area increases 3-5 times compared with common hammer ram.After processing Bearing Capacity of Composite Foundation can reach design requirement.
